FAQ

What does Generic mean?

Generic drugs are produced and distributed without patent protection. A generic contains the same active ingredients as the brand pills and is identified by its chemical name rather than its brand name. Generics are considered bioequivalent to the brand name counterpart with respect to pharmacokinetic and pharmacodynamic properties. Therefore, generics are identical to brand pills in dose, strength, route of administration, safety, efficacy, and intended use.
